Description

La commande Mesh Segmentation crée des segments de maillage séparés pour les types de surface spécifiés d'un objet maillé. La commande peut également identifier leurs paramètres qui peuvent être utiles lors de la reconfiguration d'un objet maillé.

Usage

  1. If you plan to identify the parameters of a surface type, note that the command uses the color red to mark the faces selected for this option. To see them properly:
    • The VueDisplay Mode of the mesh object ideally should be Flat lines, but should at least show faces. If necessary use the Std DrawStyle command to override this property.
    • The VueShape Color of the mesh object should not be red.
  2. Select a single mesh object.
  3. Select the Meshes → Create mesh segments from best-fit surfaces... option from the menu.
  4. The Mesh segmentation task panel opens.
  5. Optionally press one of the Parameters... buttons to identify the parameters of a surface:
    • The Surface fit dialog box opens.
    • Select one or more faces belonging to the surface:
      • Press the Region button and while holding down the left mouse button draw a region, a closed spline, in the 3D view. Faces that (partially) fall inside the region will be selected.
      • Press the Triangle button to select individual faces.
      • Optionally press the Clear button to clear the selection.
    • Press the Compute button to calculate the parameters.
    • Press the OK or Cancel button to close the dialog box.
  6. Select the surface type(s) you wish to create mesh segments for:
    • Plane
    • Cylinder
    • Sphere
  7. Specify the Tolerance values.
  8. Specify the Minimum number of faces values.
  9. Press the OK button.
  10. The command will create a group containing separate mesh objects, each a segment of the original mesh object.
  11. If the created group is empty try using the command again with modified settings.
